Using Russell's theory of descriptions

Of course some
occurrences of designators which can't be translated as individual constants
can be translated using Russell's method, paying careful attention
to scope: (E8), for example ("There is no such thing as the first
cow to jump over the moon"); and (E7) ("Buttercup is not Hugh
Rice's cow"), in which "Hugh Rice's cow" can't in fact
be translated as an individual constant (because there isn't in fact such
a thing as Hugh Rice's cow) becomes, using an obvious interpretation,

One could even
do something for (E4) (Elizabeth II became the Queen of England
in 1952") by paraphrasing it as, "It came to be the case in
1952 that [Elizabeth II was the Queen of England]", and then translating
the bit in brackets using Russell's theory of descriptions. But we could
not achieve a complete translation.
